There is no correlation between the severity of dysmorphic features and the degree of hearing loss, meaning individuals with mild malformations can have severely impaired hearing. (2001) found that 86% of patients with Hemifacial Microsomia have a conductive hearing loss and 10% have a sensorineural hearing loss. There are also reported cases of cochlear involvement and sensorineural hearing loss. In addition to ear malformations, a conductive hearing loss can be present, typically ranging from mild to severe. (2001) found that 95% of individuals with this syndrome have an ear malformation of some type. These malformations can be in the form of preauricular ear pits, complete absence of the auricle, stenosis or atresia of the external auditory canal, ossicular malformations, middle ear deformities, and incomplete pneumatization of the temporal bone. Individuals with hemifacial microsomia, also called oculoauriculo-vertebral spectrum, often have ear malformations.
